Title: Locomotive to ecp brake conversion system
Inventor: KULL ROBERT C
IPC: B60T13/66
Filed: 1999-11-16
Abstract: A conversion system enables a locomotive equipped with a conventional pneumatic brake control system to control braking on a train whose railcars each have electrically controlled pneumatic (ECP) brake equipment. The conversion system includes a power conversion mechanism, a signal conversion mechanism and two pressure reduction circuits. The power conversion mechanism converts battery voltage received from a power trainline of the locomotive to a predetermined nominal voltage. Made available to an ECP trainline that runs along the railcars, the predetermined nominal voltage is used to power the ECP brake equipment on each railcar in the train.      The signal conversion mechanism converts the pneumatic brake commands carried in the brake pipe of the locomotive into electrical brake commands corresponding thereto. Transmitted along the ECP trainline, the electrical brake commands control the ECP brake equipment on each railcar and the braking effort deliverable thereby. Part of the signal conversion mechanism, the first pressure reduction circuit is used to reduce the railcar brake pipe pressure to an emergency level when the brake pipe in the locomotive carries a pneumatic emergency brake command. The first pressure reduction circuit then pneumatically commands the ECP brake equipment to make an emergency brake application. The second pressure reduction circuit assures that the railcar brake pipe pressure reduces to the emergency level when the locomotive brae pipe pressure drops below a prespecified level.
Patent CA-2292495-A1 (CA)
Inventor: SANDIN TOMAS
IPC: H04B7/005
Filed: 1998-06-05
Abstract: The power levels of signals transmitted by base stations in a communication are controlled. Power level control commands are transmitted from a remote station to base stations. A determination is made whether the remote station simultaneously receives a first signal from a first base station and at least one second signal from at least one second base station that include substantially identical message information.  The base stations transmit first and second reports of power levels of the first and second signals, respectively, to the controller. The controller compares the first and second reports and transmits first and second commands for adjusting the power levels of the first and second signals to the first and second base stations, respectively. Also, the step size of the adjustment of the power levels of the first and second signals by the controller is reduced during macrodiversity to reduce the signalling requirements.

Title: A user interface for graphical exploration of packet trace information
Inventor: SCHAFFER STEVEN J
IPC: G06F3/048
Filed: 1998-07-15
Abstract: A user interface for a protocol analyzer or similar network management software product provides a graphical representation of the behavior of packets in a packet trace with respect to time, graphically showing a transmission time, source node and destination node. In a preferred implementation, the user interface, called a "bounce diagram", contains a time axis, and a number of node lines parallel thereto, each node line associated with a node label for a node in the packet trace. Each packet in the packet trace is represented by a packet arrow which extends from a node line for the source node to a node line for the destination node of the packet. The packet arrow is preferably color coded to indicate the size of the packet.  Preferably, there is a packet density graph which indicates in each time interval a number or percentage of packets of the packet trace transmitted during the time interval. The packet density graph may be color coded to indicate the average size of packets during each time interval. The bounce diagram is interactive and responds to a user selection of a packet arrow by displaying a pop-up window with the packet size, source and destination node addresses, transmission time, and protocol decodes for the packet. The user may also zoom in and out of the diagram by selecting an area thereof, with the diagram automatically rescaling the time axis to correspond to the time within the selected area.

Patent CA-2296950-A1 (CA)
Title: Magnetically tunable and latchable broad-range semiconductor laser
Inventor: JIN SUNGHO
IPC: H01S5/02
Filed: 2000-01-26
Abstract: The invention provides a device with an improved tunable laser structure, the structure useful with surface emitting lasers and capable of exhibiting desirable latchability. The tunable laser of the invention contains a laser structure having a lower reflector, an active laser region, and an upper reflector. The upper reflector contains a non-moveable reflector portion located adjacent the active laser region and a moveable reflector portion located a spaced distance from the non-moveable reflector portion. A magnetic material is located either on a surface of the moveable reflector portion or on a surface in contact with the moveable reflector portion, and a programmable magnet is located near the magnetic material, the magnet capable of inducing controlled movement of the magnetic material. This movement in turn induces movement of the moveable reflector portion such that the spaced distance between the moveable reflector portion and the non-moveable reflector portion is capable of being adjusted. By adjusting this spaced distance (i.e., the air gap between the moveable and non-moveable reflector portions), the phase of reflection and thus the laser output wavelength is controlled.

Abstract: At low temperatures, it is desirable to be able to heat up a wiper blade in windscreen wipers on a vehicle so as to prevent ice formation on the wiper blades and the windscreen. Within the wiper blade, there is disposed an elongate heating device (4) in thermal contact with the profile (1) of the wiper blade. The heating device (4) extends along the entire wiper profile (1) and is connected to a current source. The heating device (4) includes a temperature sensor (9, 16) which extends substantially along the entire heating device (4) and which is connected to the current source. The material in the temperature sensor (9, 16) has a temperature-dependent resistivity. Suitably, this material is a so-called NTC material, whose resistivity falls when the temperature rises. The current source includes a regulator for regulating the current supply to the heating device (4) in response to the temperature which is registered in the temperature sensor (9). In one embodiment, the NTC material (9, 16) is disposed hose-shaped about a central conductor (8), while an element wire (10) is helically wound around the NTC material. The temperature sensor, i.e. the NTC material, is connected to the regulator at the conductor (8) and the element wire (10).

Patent CA-2318172-A1 (CA)
Inventor: SCHEFFEE ROBERT S
IPC: B60R21/263
Filed: 1999-01-22
Abstract: In order to allow for at least two different rates of air bag inflation a gas generator (100) is provided with a single pyrotechnic charge (101) which is disposed in a chamber (116) in which argon or a similar type of non-toxic inert gas is stored under pressure. The chamber (116) is closed off by two or more burst discs (118, 120), only one of which is not exposed to a selectively ignitable squib (122). The non-exposed burst disc (118) is arranged to breach when the pyrotechnic charge is ignited and increases the gas pressure in the chamber (116) to a predetermined pressure. Each other disc (120) is arranged to withstand the predetermined pressure and requires weakening by exposure to the heat from an associated squib (122) before breaching will occur. The hybrid compressed gas/pyrotechnic pressure generation is such that the rate of air bag inflation varies essentially in proportion to the area of the exit port or ports which are opened by the breach of the burst disc or discs (118, 120). By limiting the number of burst discs (118, 120) which are breached, the exit port area and the rate of air bag inflation/deployment can be controlled for slow speed collisions. Breaching all or more of the discs (118, 120) maximizes port area and increases the rate of pressurization to a level suitable for high speed collisions.
